To all whom 'it may concern:

l 3e it known that I, CHARLES A. REED, a citizen of the United States, residingat St.

Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in Railway-Ties, of which the following is a specification.

My invention relates to improvements in railway ties and consists in the features of construction hereinafter described and claimed.

In the accompanying drawings forming partof this specification Figure 1 is a side elevation and partial longitudinal section of my improvement showing the shim, connecting yoke and rail in proper position. Fig. 2 is a plan of the same. Fig. 8 is a crosssection on line of Fig. 2. Fig. 4 is a cross-section on line g z of Fig. 2. Fi 5 is aplan of the of the tie with rail, yoke and shim remove Fig. 6 is an isoinetrical View of the connecting yoke. Fig. 7 is a partial elevation showing a modified form of connecting yoke. Fig. 8 is a plan of the same. Fig. 9 is a transverse section of the same on line 2-.2 of Fig. 7. Fig. 10 is a detail elevation of a modification of Fig.7, to provide support for a double headed rail. Fig. 11 is a. horizontal section on line w-I1J of Fig. 10. Fig. 1'2 is a detail of the under face of the head oi the stud-bolt for receiv ing the rail,- and Fig. l3'is a. detail oi the upper face of the spring-washer or clip in tcrposed between the bolt head and rail flange.

As shown on the drawings, the tie A is beveled on top toward each end. Upon each of these beveled portions are fitted in pairs compensating beveled shims 1, upon which is seated a tie plate 2 in the form of a yoke, which tic plate carries the rail 3.

The connection between the tie and the rail is secured by forming into the sides of the concrete tie the chases l (shown in Figs. 2 and 5) into which the pendent arms 5 of the yoke Fig. \3 are inserted and held in accurate position for proper gage ot' tra -k b v thocast iron plate (3 which bearing against is embedded in the concrete of the tie. The plate 6 is also hold in place by tho reint'orcmg rods 7 which pass through holes in the plate and are fastened to it by turning down their ends, and by the keys 'lhe chases 4 are made sulhcientl v' wide to allow of the insertion of the yoke B after the'tie and rail are in place. Who 1 the yoke l -aontal movement, while allowing it to move Undulations upon th as plished with economy out material by so placis in' place, the chases are filled taut with the wedges 9 driven between the wings 10 of the yoke and the concrete at the end of the chases. Additional support is given by tne plate 11 embedded in the concrete, through slots in which pass the reinforcing rods 12. By this means the yoke is held from horivertically.

The rail 3 is seated on the yoke 2 n" outer flange engaged in the ip 13 (:5

yoke, its inn-er flange l l u being sccnrec. stud bolt 14: which engages ohlo l5 embedded in the concrete, one end of the nut passing through a slot in the plate 11. The stud bolt passes through the hole 16 of the: yoke plate, and is provided'with a spring steel washer 17 so shaped as to engage the flange of the rail, and bent down at an an le which allows itslower edge to cut into t eshims when the bolt is tightened. This washer is so formed as to provide by its elasticity for the wave movement in the rail, but acts positively-as soon as the outer edge of. the flange is raised suthcientiy to come in direct contact with the washer l7. or teeth under side c 12) with washer (s e other when tl to prev/1t bein i The rail is secured to the f. the lip 13 and the washer l? and stud bolt Ll, while the stud bolt and washer and 'nut. 15 inserted in the slot of the plate 11, secure both rail and yoke to the tie. Adjustment of the rail to grade is obtained by shifting the shims 1 and the adjustment of the stud bolt 14, thereby providing a vertical adjustment of the rail within the distance pno-- vidcd forin the design, whilestill holding it in position from moving horizontally-- $.00 through itsbearing upon lip 13 of the yoke and the shank of the bolt 14. through the bearings of the pendent arms 5 of the yoke against the plates 6 and 11, while the tendency of the rail to overturn outward is prevented by means of the stud bolt Li and the washer 17, as well as by the bearing of the wedge 9 against the edge of the chase t and the plate 11. This object also accoming the reinforcing rods 7 and l). which are used in strengthening the concrete tie, as to .of the rail.

accomplish this purpose as well as the purpose of securing the rail, and the parts are also arranged so as to hold each other in proper position in the mold in which the tie is formed.

Figs. 7, 8 and 9 show a variation in the form of construction in which the yoke is made from a channel iron instead of a plate,

'one flange of which is turned inward to form the lip 19 While the opposite flange is turned outward to form the seat of the bolt 20. In Figs. 10 and 11 is shown the variation of the channel yoke adapted to the support of a special double headed rail by means of the bracing clips .21, formed with the outer flange engaged in the slot cut through the flange of the channel just above its intersection with the web. The upper edge of this flange of the clip is shaped so as The webs 24 of these clips are shaped as shown by the drawing to fit against the web of the rail and the shape of the groove in the reversed head. The flange of the clip is shaped at 25 so as to bear against the very top of the flange of the channel. The depth of the groove in the under side of the head is so proportioned that in driving the clips into place, the shoulder 25'will spring outward the flange of the channel within the limits of elasticity while the end 23 of the clip is passing under the head and into the roove made to receive the same, the flange 0 the channel of the yoke returning to position through its elasticity holding the same in place. The reinforcing rods 7 and 12 are carried in the notches of the plate 18 and thus held from displacement in the construction of the tie itself, the plates being heldin place by a wire 26 which is connected with the bottom of the mold into which the concrete is filled and cut off even with the top of the tie when it is removed from the mold. In the construction shown in Figs. 7 and 8 the cross-bar or rod 27 is substituted for the plate 6 in Figs. 1, 2 and 3 thereinforcing rods 7 being secured to the bar by being bent partially around the same as shown.

In the construction shown in Figs. 10 and It only one shim 28 is illustrated instead of two. In this case slots 29 are provided in the shim through which the securing bolts are passed. 5

The methods of assembling the parts for original and new construction, and the method of maintaining "the track after the construction is in place, are as follows: In new construction the ties are placed in proper position, the shims are placed upon them, and the yoke upon the shims, the wedges 9 being then driven into place. The rail is then set upon the yoke with the flange engaging the lip 13, and the stud bolt inserted with the washer 17 in place and turned to fit a groove on the under side of the head down until the space between the outer edge of the lower flange of the rail and the washer is about one-eighth of an inch.

In placing a tie in an old track, the yoke is i set in place in its chases in the tie and the tie slid underneath the rails to its proper position. The yoke is then raised and canted outward until the lip 13 passes over the flange of the rail, the wedges 9 are then driven into place and the stud bolt inserted l with the washer 17, and screwed down to the 5 position described above. It is the intention t that the gage of the track shall be absolutely fixed by the bearing of the arm of the against the face of the plate 6. Too 8() be readily obviated by the edges between the bearing 1 yoke 5 wide gage can driving of steel w face of the plate (3 and the edge of the arm 0.

In maintaining the track the gage being made accurate the rails are held from spreading by the bearing from steel to steel, and any narrowing of the gage is adjusted by the wedges 9.

In maintaining the track the proper grade or surface is cared for as follows: The track inspector by tapping with a hammer the outer end of the beveled shim will drive it inward and thereby take up any looseness caused by wear on it by the bearing of the yoke. It the tie is not firmly bedded upon the ground underneath, its weight through the stud bolt 14 bearing on the spring clip 17, will spring the clip downward so as to close up partly or wholly the space properly left between it and the outer edge of the 100 flange of the rail. When this space is less than it should be, the inspector will back up the stud bolt 14, thereb allowin the tie to settle into its place, w en by a low upon the outer end of the shims the bearing 105 is again secured between the yoke and the tie. When it is lowered into proper position, the outer edge of the s ring clip 17 will out into the shim as the be t is tightened or the shim driven, and hold the shim in proper po- 11o sition, the angle of the bend in the clip 17 being such as to prevent any tendenc to tighten the wedge undul by reason 0 the motion caused by the un ulation of the rail under traffic.

If the tie in becoming firmly bedded is canted so that the seat for the shims is not parallel with the rail, the driving of one shim farther than the other will increase the bearing surface between yoke and shims.

he construction of the stud bolt 14 with undulations or teeth on the underside of the head engaging with the teeth or undulations in the steel clip 17, forms a lock that prevents vibrations of the rail under traitic from 125 loosening the bolt.

I claim- 1. In combination, a beveled railway tie,

a compensatingly beveled rail-supporting shim, a rail seated on said shim, and means 130 as es rail-securing stud-bolt, and a spring clip engaged by the head of said bolt and engaging the rail base and shim.

In combination, a beveled railway tie, a compensatingly beveled shim adjustable thereon, a rail seated on said shim, a railsecuring stud-bolt, and a spring clip engaged by the bolt head, one end thereof bearing upon the rail base and the other adapted to engage and hold the shim in v adjusted position.

'of a suspended tie and to indicate its displacement to the eye. u

-5. In combination, a beveled railway tie, a compensatingly beveled rail supporting shim, and a vertically adjustable channelshaped Jyoke having depencling ends engaging sai tie.

6. The combination with a beveled concrete tie, and compensatinglybeveled railsupporting-shims, of a vertically-adjustableyoke seated upon said shims and having de pending ends arranged in chases in the sides of said tie, bearing plates for the edges of i said depending yoke ends, and rods interconnecting the bearing plates in opposite ends of said tie.

7. In combination with a beveled railway tie and compensatingly beveled railsup-- imiting-shims, a vertically-adjustable, channel-shaped yoke having depending ends adapted to engage chases in the sides of said tie.
